However, according to CEA-861-D no SAD is needed for basic audio(32/44.1/48kHz stereo 16-bit audio), which is instead indicated with abasic audio flag in the CEA EDID Extension.

The flag is not present in ELD. However, as all audio capable sinks arerequired to support basic audio, we can assume it to be alwaysavailable.

Fix allowed audio formats with sinks that have SADs (Short AudioDescriptors) which do not completely overlap with the basic audioformats (there are no reports of affected devices so far) by alwaysassuming that basic audio is supported.
